Description

The The invention relates to a fastening clip, in particular for Attaching a seal enclosing a window pane and / or guide profile is used on the body of a motor vehicle. The fastening clip is provided with a holding part, which can be fastened to a first component and about an axis of rotation parallel to a mounting direction is rotatable. In addition, the mounting clip with a male part provided, which can be fastened to a second component and in the fastening direction connectable to the holding part. The holding part is with at least a locking leg provided in a direction of attachment orthogonal first transverse direction is elastically deformable and a sales area, at which the plug-in part can be fixed in a form-fitting manner for connection to the holding part, having. In addition, the holding part has a belt portion on which the Detent leg is pivotally mounted.

Such a fastening clip discloses the DE 33 24 762 A1 , The known fastening clip is used for detachable connection of stacked components and is composed of a locking part and an insert. The insert is arranged torsionally secure in a hole provided with a rectangular cross-section. Detent leg representative walls of the insert are provided with bevels to ensure that the insert snaps into place at the edge of the hole. After the insert is secured to a plate having the hole, the locking member is inserted into the insert. For this purpose, the locking part has a shank or hook portion which is provided with protrusions extending in a first transverse direction. After insertion into the insert, the locking member is rotated 90 degrees. The rotation of the locking part has the result that the projections come to rest on shoulders of the insert and cause in this way a positive connection between the locking part and the insert. The end faces of the projections also push the walls apart and thus ensure a tight fit of the insert.

When disadvantageous in the known mounting clip has a relative elaborate assembly, which stems from the fact that it is used to connect the Locking part with the insert of a turning operation requires.

In addition, in the DE 198 30 752 A1 a fastening clip for connecting two plate-shaped components described. The known fastening clip has a foot portion which is designed as a flange which can be applied to an outer side of the first component. The mounting clip is also provided with a holding section, which consists of four, offset by 90 ° to each other legs. The legs are separated by slots and have shoulder surfaces forming a support surface. The resiliently configured due to the slots legs allow to introduce the holding portion in an opening of the second component, in such a way that the holding surface formed by the shoulders of the legs rests on the edge of the opening on the side facing away from the first component. In this way, a positive connection results, which holds the first component to the second component.

The effectiveness of the positive connection caused by the fastening clip depends primarily on the size of the holding surface. Because the larger the holding surface, which bears against the edge of the opening, the greater the withdrawal force which is required to pull the holding portion out of the opening of the second component. Decisive for the effectiveness of the positive connection is still the deformability, which must have the holding portion in order to be inserted into the opening of the second component can. The deformability is determined except by the material from which usually made by injection molding fastening clip, especially by the shape of the holding section. The requirements placed on the shaping are, on the one hand, to ensure the greatest possible pull-off force and, on the other hand, to minimize the mounting force required to push the holding section through the opening of the component. The springy legs of the DE 198 30 752 A1 Although known fastening clips allow easy insertion of the holding portion in the opening of the second component and thus a relatively low assembly force, but a disadvantage is a relatively low withdrawal force, which results after locking the shoulders.

Furthermore, the disclosure DE 100 08 565 A1 a fastening clip which serves to fasten a component consisting of a relatively soft material, for example an acoustic insulating mat, to a harder component, for example the hood of a motor vehicle. The known fastening clip has for this purpose on a foot portion which forms a relatively large-scale mounting plate which is materially connected, for example by gluing or ultrasonic welding, with the component to be fastened. The mounting clip is also provided with an elastically deformable holding portion by two in the manner of a saddle roof ordered thighs is formed. One of the legs is fixedly connected to the foot portion, whereas the other leg is spaced by a gap from the mounting plate to ensure the deformability of the holding portion. The moreover articulated legs have edges, which are provided with rectilinear locking grooves. Although in this way relatively large locking grooves contribute to a reliable positive engagement, but at the same time prevent a non-destructive disassembly of the mounting clips.

Of the Invention is based on the object, a mounting clip create, with a relatively large deduction by a simple assembly and a non-destructive disassembly distinguishes.

to solution this task is with a mounting clip with the above Characteristics in accordance provided with claim 1 according to the invention, that the locking leg with a free end, which is the belt section facing away from and has a bearing surface adjacent to the first component, and a conically tapering in the fastening direction spreader, by the locking legs during insertion of the male part in the Holding part is deformed in the first transverse direction, provided is. The positive connection between the male part and the shoulder surface is by turning the holding part by a predetermined safety angle solvable.

Of the invention Fixing clip is based on the knowledge, by a two-part construction at a relatively large Abziehskraft both a simple installation and a non-destructive Dismantling to achieve. The two-part structure allows the holding part on the first component, for example, the body a motor vehicle to attach and separately the male part the second component, for example, a sealing profile to arrange. By insertion the male part in the holding part can then be the second component form-fitting connect to the first component. The spreading surface ensures that the locking leg deformed by the male part targeted in the first transverse direction becomes. Due to the deformability of the locking leg in the direction orthogonal to the fastening direction first transverse direction a plug connection is realized, which ensures a simple and practical installation. In contrast, is a non-destructive disassembly of the inventive Fastening clips primarily due to the fact that the fit between the male part and the holding part by turning the holding part can be released by a predetermined safety angle. With dissolved positive locking It is not necessary to overcome a pull-off force to the male part to be separated from the holding part. For this reason, it is possible to Rastschenkel a form to give the existing positive fit between male and female part a relatively large peel force and thus a reliable Secured attachment of the second component to the first component.

advantageous Make developments of the inventive fastening clips things the claims 2 to 15

So It is advantageous if the safety angle is approximately 90 °. Because In this case, it is ensured that during relative movements between the first component and the second component, for example, by Vibrations are caused, sufficient coverage present between the male part and the shoulder surface of the holding part is that an unintentional release of the Positive locking prevented.

From Advantage is further, if the holding part a circular belt section, on which the locking leg is pivotally mounted, has. The swiveling Arrangement of the locking leg guaranteed sufficient deformability in the first transverse direction, so that for connecting plug-in part and holding part a relatively small Installation force is required. To make a swiveling arrangement of Locking leg on the belt section To realize, it is advantageous to the locking legs in the area of the belt section with to provide a depression. The recess allows a film-like hinge form, which ensures a targeted deformation of the locking leg.

In a preferred embodiment of the inventive fastening clips has the holding part at least one wall, the recess by a recess is spaced from the locking leg. The wall contributes to one sufficient Stifflgkeit of the holding part, which provides a reliable attachment on the first component ensures. The recess, however, guaranteed an unhindered deformation of the locking leg.

In order to fix the holding part to the first component, the wall has a first end, which is connected to the belt portion, and a second end, on which a preferably polygonal designed holding plate is arranged on. The configured as a hexagon retaining plate serves on the one hand to attach the holding part to the first component. On the other hand, the holding plate makes it possible to grasp the holding part by means of a tool, for example a wrench, so as to rotate the holding part about the rotation axis. Upon rotation of the holding part to the safety angle can thus solve the male part of the holding part.

Farther It is advantageous if the retaining plate by a preferably bent trained spacer is connected to the wall, wherein the spacer by a preferably approximately oval opening of the first component extends. The spacer connects the wall with the holding plate in the region of the opening formed for example as a slot. This allows the Wall and the retaining plate on opposite sides of the first component to arrange. In this case, an approximately oval or elongated opening contributes to this at, the holding part in the opening introduce, for a preliminary To achieve fixation of the holding part to the first component. To this Purpose, the locking leg advantageously has a contact surface, at an inner edge of the opening the first component adjacent, wherein the retaining plate on the Detent leg remote from the first component on an outer Edge of the opening is applied. The holding part leaves in this way between the contact surface of the locking leg and the Clamp the retaining plate to the first component.

Conveniently, the retaining plate is provided with a passage which allows the male part through the holding plate and the opening of the first component through into the holding part to a positive connection between the male part and the shoulder surface of To bring locking leg.

In a preferred embodiment of the inventive fastening clips the locking leg has an adjoining in the fastening direction of the expansion surface centering on. The centering surface contributes to that in aligning the male part with respect to the shoulder surface of the locking leg, so that is a reliable Form fit between the holding part and the male part results.

The Plug part has expediently one attachable to the second component foot portion and a adjoining in the attachment direction to the foot section Hook section on. The hook portion serves to form fit in to engage the holding part. In contrast, the foot section serves to fix the male part to the second component. These functional division of the male part allows the foot section on Practical way cohesively, For example, by injection molding, to connect to the second component.

Around a reliable one To ensure positive connection between male part and holding part has It also proved to be advantageous if the male part a following in the attachment direction to the hook portion Has centering. The centering acts with the Centering of the Locking leg together to align the male part against the holding part.

In a preferred embodiment of the inventive fastening clips the hook portion has a first width in the first transverse direction and in a second orthogonal to the first transverse direction Transversalrichtung a second width, the first width is greater as the second width. This uneven design of the hook portion comes especially to bear, if the holding part in an advantageous Way two opposite arranged locking legs, the centering surfaces in a minimum distance apart, wherein the minimum distance greater or equal to the second width of the hook portion. Because in this case can be the connected to the holding part plug-in part when rotated by one Safety angle of 90 ° in bring a position that allows the hook section between the centering surfaces to pull the locking leg out of the holding part.

details and provide further advantages of the inventive fastening clips from the following description of a preferred embodiment. In which the embodiment illustrate only schematically representing drawings in detail:

1 a longitudinal section through the inventive fastening clip, which shows the male part and the holding part loosely connected to each other;

2 a longitudinal section according to 1 showing the male part and the female part in positive engagement;

3 a section along the line III-III in 1 ;

4 a section along the line IV-IV in 1 ;

5 a section along the line VV in 1 and

6 a section along the line VI-VI in 1 ,

The in the 1 and 2 shown fastening clip is made of a male part 10 and a holding part 20 together, each made by injection molding, for example, made of plastic are. The plug-in part 10 has a foot section 11 on, the cohesive in a rubber-elastic sealing profile 40 is embedded. The plug-in part 10 is further with a in a mounting direction x to the foot section 11 following hook section 12 Mistake. The hook section 12 has a first width b ₁ in a first transverse direction y orthogonal to the attachment direction x and a second width b _{2 in} a second transverse direction z orthogonal to both the attachment direction x and the first transverse direction y. The first width b ₁ is greater than that of the second width b ₂ . To the hook section 12 closes in the attachment direction x a centering 13 on, which has a free end of the male part 10 forms. The width of the centering section 13 in the second transverse direction z corresponds to the width b _{2 of} the hook portion 12 ,

The holding part 20 has two oppositely disposed locking legs 21 . 22 on. The locking legs 21 . 22 are elastically deformable in the first transverse direction y. For this purpose, the holding part 20 a circular belt section 26 on, on which the locking legs 21 . 22 are arranged pivotally. The locking legs 21 . 22 are in the area of the belt section 26 with a depression 27 provided, which forms a film-like hinge to a targeted pivoting of the locking legs 21 . 22 to ensure y in the first transverse direction. The deformability of the locking legs 21 . 22 can thus be through the design of the recess 27 influence.

As the 1 and 2 can also be seen, the locking legs have on one of the recess 27 opposite free end of a contact surface 32 on, in a in the first transverse direction y extending flat portion of the body 50 of a motor vehicle. The contact surface 32 runs in an initial state of the locking legs 21 . 22 slightly inclined to the first transverse direction y. The inclination angle of Anlageflä surface 32 is such that the contact surface 32 in the pivoted state of the locking legs 21 . 22 almost parallel to the body 50 extends. The contact surface 32 goes in an expanding direction in the mounting direction x conically tapered expansion 24 above. To the spreading surface 24 closes in mounting direction x a centering 25 at, which runs approximately parallel to the mounting direction x. The arranged in this way opposite centering 25 the locking leg 21 . 22 have in the initial state of the locking legs 21 . 22 a minimum distance c from each other, as from 1 is apparent. The minimum distance c is greater or at least equal to the width b _{2 of} the hook portion 12 of the male part 10 , The centering surface 25 leads to a sales area 23 , which are substantially in the first transverse direction y and thus approximately parallel to the contact surface 32 extends.

To ensure unhindered pivoting of the locking legs 21 . 22 ensure the holding part has 20 two oppositely arranged walls 28 on, through recesses 29 from the locking legs 21 . 22 are spaced, as from the 5 and 6 is apparent. The walls 28 are at a first end with the belt section 26 connected and have at a second end spacers 31 on which a holding plate 30 is arranged. The spacers 31 are curved and extend through a slot 51 trained opening of the body 50 , in particular in 4 can be seen. In contrast, shows 3 that the holding plate 30 designed as a hexagon and with a centrally arranged passage 33 is provided. The circular cross-section passage 33 has a diameter d which is greater than the width b _{1 of} the hook portion 12 , In this way, the plug-in part can be 10 through the passage 33 through into the holding part 20 introduce.

The fastening clip described above serves the sealing profile 40 at the body 50 to fix. For this purpose, first the holding part 20 in the slot 51 used. When inserted, the contact surface is adjacent 32 the locking leg 21 . 22 to one the slot 51 surrounding inner edge 52 the body 50 at. The holding plate 30 on the other hand, the slot is on one side 51 surrounding outer edge 53 on the locking legs 21 . 22 facing away from the body 50 on, like from the 1 and 2 is apparent. The holding part 20 This way, between the retaining plate 30 and the locking legs 21 . 22 positive fit on the body 50 held. As 4 to recognize, are through the slot 51 extending spacers 31 dimensioned so that a certain freedom 54 to the slot 51 bounding edges 52 . 53 remains. The open space 54 allows the spacers 31 inside the slot 51 to move and thus the holding part 20 to rotate about an axis of rotation A parallel to the mounting direction x. Turning the holding part 20 simplifies the insertion and removal of the holding part 20 in or out of the slot 51 and also allows one between the male part 10 and the holding part 20 to solve caused positive connection.

This is due to the fact that for securing the sealing profile 40 at the body 50 the plug-in part 10 so in the holding part 20 is introduced that the hook section 12 when hitting the spreader surface 24 the thigh 21 . 22 pivoted in the first transverse direction y and in the holding part 20 imported state form-fitting on the shoulder surface 23 is present, as from 2 he is visible. The one with the centering surface 25 the thigh 21 . 22 cooperating centering section 13 of the male part 10 Make sure that the thighs 21 . 22 be swiveled evenly. Will the holding part 20 rotated by a safety angle α of about 90 °, so come the legs 21 . 22 lie in the second transverse direction z. Because the minimum distance c between the centering surfaces 25 the thigh 21 . 22 greater or at least equal to the width b _{2 of} the hook portion 12 is in the second transverse direction z, the positive connection between the hook portion 12 and the sales area 23 solved with the result that the male part 10 from the holding part 20 and the slot 51 pull out.

Deriving from the male part 10 and the holding part 20 assembling clip is thus characterized by a non-destructive disassembly. A simple turning of the holding part 20 is formed by the trained as a hexagon retaining plate 30 ensures that a gripping of the holding part 20 with a tool, such as a wrench allows. The two-part mounting clip also offers the advantage of easy installation, since the male part 10 due to the elastic deformability of the locking legs 21 . 22 by a practical plug-in form-fitting with the holding part 20 can be connected. Not least, ensure the thighs 21 . 22 in the pivoted state a reliable positive connection between the with the sealing profile 40 cohesively connected plug-in part 10 and on the body 50 attached holding part 20 which takes into account the demands for a relatively high deductibility.
